This research investigates how sign language experience reshapes the brain’s visual system. MRI studies show expanded hand-processing regions and reorganised face areas in both deaf and hearing signers, even when learning occurs in adulthood. The findings highlight neural plasticity and reveal how visual language transforms perception and brain organisation.

This research develops a universal writing system for sign languages, enabling Deaf communities to record and edit stories in their own languages. The system combines handwritten simplicity with digital notation, capturing facial expression, body movement, and spatial structure to reflect the full linguistic richness and visual complexity of signed communication.
